Does Resizable Bar Make Games Faster?

Is resizable bar important for GPU performance? Turns out it is. At least a little bit. In this video we'll find out how much. This is a follow up to the video I did a while back about upgrading Nvidia GPU Drivers. I kind of messed up in that video and this video is an update.

Whilst showing purely FPS number differences with testing is useful - including frame timing consistency in your results, and any effect that Re-Bar has on that, would have been more useful info to be honest. As it's frame timing consistency that you can actually feel in a game, not fps averages. Other than that, good video, and love your content dude ! 👍

[@mohamednaflan4361]

Also the 1% and 0.1% lows, I think we can see a big diffference here since rebar is a memory related feature.

[@reapergr7gaming653]

Just to let everyone know, in newer versions of the Nvidia Profile inspector there are no 0x000F00BA etc anymore. Rebar is now located under '5- Common'-> and the three options are labelled 'rBAR - Feature', 'rBAR - Options' and 'rBAR - Size Limit'. “

[@chasethefeel]

no point forcing it on nvidia puts it on when it does something.

[@ristyp]

This made me realize that my resize bar was no enabled. I bought my graphics card through a HP Omen, so finding the driver was quite the job. So glad I finally figured it out, thanks a lot!

[@ipKonfig]

It's shocking how Resize Bar technology wasn't a thing already implemented into games for years. It's like someone got lazy in the dev world and now we're having to wait for games to support it or update their game to support it.

[@gearfriedtheswmas]

The answer is consoles holding everything back.

[@Spladoinkal]

It can't be implemented into games unless the hardware and the hardware's drivers can make use of it. Game devs had to work with what they're given. Now you could argue that the hardware/hardware drivers should've made use of it years earlier and I'd agree there, but there may have been a reason for the limitation we're not aware of.

[@CyberCPU]

I think the reason it hasn't been a thing until now is because games didn't really need it. We've experienced a huge evolution in realism in games just recently and that's what's made this more of a requirement.

[@Spladoinkal]

@CyberCPU Tech this is true too. Cpu usage wasn't really an issue prior to huge open worlds.

[@josir1994]

It's shocking you didn't jump into the dev world and solve this obvious problem.

[@regwatson2017]

Thanks for this info. You are the first reviewer that alerted me to how to check if "Resizable Bar" was on and then easy to follow directions to turn it on when I found mine was off. I assumed it was already on having a newly built system and GPU. Resizable Bar is a silly bloody name by the way !

[@IANC4EVER]

You're very good at explaining and breaking things down in a way that everyone can understand - A rare gift, which indicates you know your stuff well. Thanks! 👍

[@smartinro.]

In ASUS bios there is an option at top right that says "Resize BAR" (Shown at 5:43). If you use that option, it changes all the related settings automatically to enable it.

[@CyberCPU]

True. I still like showing how to do it manually. Not everyone has an ASUS board and that setting. By doing it manually it's easier to follow the steps on a wider range of hardware.

[@smartinro.]

Hi, I've come across a few of your tutorials recently via search. Just want to say thanks for keeping it noobish. Many techsperts skip small details, leaving me 1/2 informed, confused, frustrated. Those who already know this stuff don't need to watch/learn (but prob do anyway just to critic u). Will give it a go with FiveM & RedM. Subbed. Look like u "might" be a bike owner? I've got a Fury.

[@imad1996]

This is an awesome video. I did not only click like but subscibed to your channel. It is best that you do a small research to explain what a resizable bar is and explain the pros and cons of this feature. Awesome work. Thank you. I do not appreciate those tons of KZbinrs who tell you, "let me tell how you can achieve 1000fps more and showing a Pic of 10fps before and 2700fps after"😂😂😂

[@caretaker2185]

Maybe it's just me, but I kept hearing "GDP partition"... If I'm not crazy - it's "GPT" FWIW.

[@theplayernkc]

3:00 It's not correct that you need an Intel 10th Gen or newer processor. I have two Z390 motherboards with a 9 series processor that will allow for Resizable Bar. The two motherboards are a ASUS TUF Z390-PLUS GAMING (WI-FI) and Gigabyte Z390 DESIGNARE. It just depends on the motherboard manufacturer to put out a bios that allows this on older processors.

[@CyberCPU]

Good to know, thanks for the info.

[@conyo985]

The only game I know that gains a lot with Resizable Bar is Dead Space Remake. That's why in the latest Nvidia Drivers it was enabled by default.

[@itsdeonlol]

With Intel ARC you must to have RE-BAR enabled.

[@tuxpowerpc]

Excellent video. I wonder if you would mind doing a part two and show how to download and install NVIDIA Profile Inspector. Also, I run Linux on my main machine and do not believe this app even applies. That said, I do have an equally spec'd Windows PC for certain uses including a few games. Last, I noticed when you showed how to set changes back to default, you did not mention to apply the changes which most should figure out, but some may miss. Love your content and how you present, it's easy to follow and listen to. Thanks!

[@CyberCPU]

The Nvidia profile inspector is a portable app. It doesn't need to be installed. Linux is far behind Windows when it comes to gaming. I don't believe any of this is relevant to Linux. However I gave up on Linux gaming ages ago. It's better now but nowhere near good enough to rely on it as a gaming OS. You don't have to apply the changes when you revert to defaults. At least I don't believe you do. I believe the reset button does that automatically. I might be wrong though, you have me doubting myself. I may have to check it out.

[@Steezy76]

I just disabled resizable bar in bios a few days ago and saw a big decrease in ram latency on benchmark tests. I am leaving it off as I'd rather have higher .1% fps than higher average fps. 13900k and 4080.

[@michaellvoltare]

I've read someone saying their cpu usage decreased as well by 20% after disabling rebar. With these fps "gains" I'd rather have it off as well.

[@ZetsumeiIkari]

[@-Aeveris-]

Thanks man, this video helped me a lot; to activate rBAR, I would first have to update my BIOS - and that's too much effort for the small increase in performance.

[@domedsky]

Would like to see results from CPU intensive games like Star Citizen

[@DJaquithFL]

The resizable bar performance depends on the game but for the most part I would recommend enabling resizable bar in the BIOS. You certainly can look up benchmarks with and without. I only play one game MW2 and at least on my RTX 4090 I'm gaining about 10 FPS @ 3440x1440. CPU-Z JJU8GT

[@dragonwikgaming582]

nvidia auto dissables it for games the worsen with it on anyways so mind as well just keep it on.

[@DJaquithFL]

@@dragonwikgaming582 .. It does unless you override it.

[@DJaquithFL]

If you Enable (Auto) the Resizable Bar in the BIOS, CSM in Auto will work correctly. in other words, one change versus several changes. At least that's the way I do it and then verify.

[@richardernest9151]

I guess a better check if resizable bar is turned on.

[@techwolfcave]

Thanks, this is such a great help.

[@LZeugirdor]

AMD has already enabled Resizable Bar functionality on 5000 series graphics cards. I highly recommend using the custom graphics driver Amernime Zone. It functions very well, and allows you to enabled DXNavi on 5000 series graphics cards, which not only speeds up loading times but also reduces stuttering and increases 1% and 0.1% lows. The 5600 XT is known to have an issue with limited 1GB Bar size, however this can be overcome by bios modding. I don't recommend this unless you have a dual bios board, and even then DXNavi has more of an impact in my opinion on RDNA1 than ReBar does.

[@Winkmyster]

At first look people may misinterpret you as a biker, when in reality you are a wizard, the distinction is your vernacular and your t-shirt.

@7:47 CPU -G haha loved it :P

[@MagnumForce51]

Kind of a shame you have to disable CSM for this. I have a dual monitor setup and on my rig if I disable CSM the wrong monitor shows the UEFI boot logo and such. Now granted my PC is 4th gen Intel so resizable bar will never be an option anyways but I suspect the monitor behavior might become a problem if I ever upgrade to a system that does. :(

I know you mention it but the GPU BIOS needs to support it too. I have GTX 980 Ti and it’s not supported regardless of the driver version. The problem is the latest MSI BIOS now has resizable BAR enabled by default. I just happened

for Nvidia is not a large improvment, the only diferrence I saw is that my motherboard bios now runs at the native resoluition of my monitor

[@Steve30x]

3:36 this isn't correct. I'm using an AMD RX5700XT , MSI X470 Gaming plus with the latest ueif bios update , AMD R5 5600X and 16GB DDR4 3200 ram. I have resizeable bar enabled in the uefi and in the last few AMD driver releases. With resizable bar enabled I also notice games load way faster with my NVME drive.

[@CyberCPU]

Good to hear. My videos are filmed 2 to 3 weeks before they are published. I did mention in the video that ATI was expanding support for older cards.

[@Steve30x]

@@CyberCPU I couldn't enable resizable bar when I had an R5 2600 but I upgraded to an R5 5600X a few months ago. I had the R5 2600 for over three years. I know I could haven't saved money by buying the 5600 but I wanted to buy the 5600X since it was released. I fought with myself when buying the CPU 😂. I know it's only worth 2 or 3 fps more but I had to have it. Also I'm using pbo curve optimized negative 24 and the CPU boosts to 4.85GHz with ease without going above 65C.

Does this not increase load capacity on your GPU and CPU causing higher Temps and shortening life span?

No, if anything it should lower the loads on your CPU.

[@ThePharaz]

Any idea when or if NVIDIA will make resizable bar available for RTX 2080 super?

[@CyberCPU]

I don't know if that's even a plan. It would be nice but I believe it's a tech that is only available on 30 series and up. It's my understanding that this Tech requires a vbios update. Since Nvidia is more of a GPU OEM to a wide range of manufacturers it would require those manufacturers themselves to update and test their own vbios. Aside from a few exceptions ATI makes their own GPUs so it's easier for them to implement support on older GPUs. For NVIDIA it would be a monumental task for a GPU that they don't really even produce anymore. So it's probably not going to happen.

[@outsideredge]

I've done all these steps but no matter how many times I turn on Resize BAR and Above 4G Encoding on in my B460 mobo it still says Resize BAR is off in GPU-Z

Fps isn't really what resizable bar is for... it's for better cpu gpu clock speed... I get 8ms gpu time and 6ms cpu time... once I enable rebar I get 4ms cpu 4ms gpu on the same settings in warzone... fps is always different because of background apps and because of game server inconsistencies... rebar is very good if the game supports it... Google it... if it's supported for the game Your wondering about... people will be talking about it

[@CyberCPU]

Driver updates don't always contain specific optimizations for specific games but they do optimize the GPU itself and make it more efficient. Not updating drivers is leaving performance on the table in most cases. Might as well get what you paid for by a free driver update. Just the performance increase that I got in Cyberpunk and Control alone many people would buy a new GPU to achieve. I was actually blown away at that more than anything else.
